1 Kings 16:21-26

21Then the people of Israel were divided into two factions: half of the people followed Tibni son of Ginath, making him king, while the other half followed Omri.

22But the people following Omri prevailed against the people following Tibni son of Ginath. Tibni died, and Omri became king.

23In the thirty-first year of King Asa of Judah, Omri began to reign over Israel, and reigned 12 years, six years in Tirzah.

24Then he bought the hill of Samaria from Shemer for two talents of silver, and built a city on the hill. He named the city that he built Samaria, based on the name Shemer, the owner of the hill.

25But Omri did what was evil in Adonai’s eyes, and acted more wickedly than all who were before him.

26For he walked in all the ways of Jeroboam son of Nebat and in the sins that he had caused Israel to commit, vexing Adonai God of Israel, with their useless idols.
